Specification of Letters Patent.

Patented Aug. 3, 1920.

To all whom it me concern:

Be it known til at We, ALFRED L. Knoxv- QUEST and JOHN C. TALIAFERRO,citizens of the United. States, residing at Chicago, in the county ofCook State of Illinois, and Baltimore Maryland, have invented certainnew and useful Improvements in Can-Closv more particularly to a canclosing Ina-chine wherein an end or a cover is secured to the can bodyby a'double seaming mechanism.

An object of the invention is to provide a continuously operating canclosing machine wherein the can body travels continuously in a forwarddirection and in a curved path and wherein means is provided forassembling can ends or covers and the can bodies, for rounding up thecan body for seating the can end or cover in the can body and for doubleseaming the end or cover to the can bod A further object of theinvention is to provide a machine of the above character with means formarking the cover as it passes from a stack holder to assembled positionrelative to the can body to which it is to be attached.

A still further object of the invention is to provide a machine of theabove character wherein the can body and its cover are assembled by amechanism located outside of the seaming machine, which assemblingmechanism includes-devices for gradually lowering the cover on the canbody as they move forwardto the seaming machine, so

that said cover registers with and rests on the can body as it entersthe seaming mane. v t A still furtherobjectof the invention is toprgyjdea machine of the above character wherem theassemhling mechanismand the seaming mechanism 'coiiperate in rounding up thecanbodyipreparatory to the seating of the cover in t' e can body by thechuck of-the seaming-ma hine.

Another object of the invention is to pro vide a machine of the abovecharacter wherein the cover or end is attached to the can body by asingle seamin roll having a first operation groove i'ormet therein and asec ond operatiodgroove formed therein, said grooves being disposed oneabove the other and means is provided for moving the seaming roll andcan body relative to each other for bringing about the operation of thefirst and second seaming grooves in succession.

Still another object of the invention is to provide a seaming machinewherein the seaming roll is fixedly secured to the spindle which carriesthe same and means is provided for positively operating the spindle, thespindle being of suflicien-t length so that the metal thereof may yieldto permit the seamin roll to pass the side seams of the can bod thusdoing away with all yielding pads or cushions heretofore used or suchpurpose.

Still another object of the invention is to provide a seaming mechanismwherein the seaming roll is provided with first and second operationgrooves, which seaming roll is positively operated by a can having anadjust able section for varying the tightness of the first operation andwherein also the seaming roll may be bodily shifted relative to itssupporting spindle, so that the tightness of both operations may besimultaneously varied.

Still another object of the invention is to provide a seaming machine ofthe above character wherein the seaming roll has first and secondoperation grooves and wherein said seaming roll is operated positivelyby a cam with means for permitting the withdrawal ofthe seaming rollfrom the can between the first and second operations, so

.that the can may be removed for inspection. 7

Another object of the invention is to provide a closing machine whereinthe can.

travels continuously forward in a curved" path in an upright position,which machine has means for rounding up the canbody; for assembling thecover and the can body, for seating the cover in the can body while itis rounded up and for seaming the cover to the can bod with :rmechanismfor timing the can bodies as theyare delivered to the as semblinmechanism, which marks and '5 places t 1e cover on the can body, whichtimlng mechanism presents the can body to the view of the operator forinspection.

A'further object of the invention is to provide a machne of the abovecharacter in which the timing of the cans. is brought about by rotatingtraveling supports for the Mean odies, which supports have different"-speeds of travel, so that the can bodies are gradually shifted by arotation thereof until brought into contact with the timing fingers.

Still another object of the invention is to provide means associatedwith the timing mechanism for determining whether covers are to be fedfrom the stack, so that covers will only be fed as a can body passes tothe can body and cover assembling mechanism.

Still another object of the invention is to provide a marker for amachine of the above character, which marks the cover while it istraveling and which marker. includes means whereby it may be readilychanged so as to vary the identifying mark placed on the cover.

These and other objects will in part, be

obvious and will in part be hereinafter more fully described.
